Pond Water Collection Tips • Look for signs of life (plants and animals) • Collect water using a ladle or disposable container, making sure to get some sediment from the bottom • Use tongs to collect aquatic plants - look for algae and floating or rooted plants • Don’t leave your container sealed with a lid for long - give your organisms light and air LOUISIANA STATE UNIVERSITY
